A coupon code (with the member’s username) is generated for each member of the network. The member can give this coupon code to new prospective users. Anybody who makes a purchase on the shop using the coupon code of a network member would automatically get a discount equal to the percentage value specified in the Coupon Code value field in the General Settings.
The referring member will also be stored as the sponsor of the new user. Even if the new user does not join the network at the time of initial purchase / signup, the system would automatically pickup the referring member as being the sponsor of the user on the Join Network page available for Joining the Network for regular shop customers.
